Jazi – Ransomware
Jazi is a destructive software application functioning as typical ransomware. Michael Gillespie, the popular malware researcher, very first found this new name in the DJVU ransomware family.
Jazi was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is effectively accomplished, the users are unable to get access to them. Jazi ransomware adds its own “.jazi” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Jazi, will be entitled as “price_list.xls.jazi”. Once the encryption is achieved, Jazi puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by _readme.txt requesting the random os very comparable to the notices provided by other ransomware hazards belonging to the DJVU family. The caution basically shows that the data has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.
The approach to secure the files utilized by Jazi is not totally investigated. However, there is no doubt that each computer owner might be provided a special decryption key, which is definitely special. It is extremely tough to recover the data without the appropriate type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Jazi ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Jazi virus into the world wide web. In order to acquire the key and restore the essential information, the users are told to contact the scams by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people must call the Jazi authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so individuals will obtain a 50% discount, for that reason, the ransom quantity falls to $490.
